Abstract (en)
[origin: US2020044261A1] The present invention is a carbon material for a catalyst carrier of a polymer electrolyte fuel cell, which has a three-dimensional dendritic structure, and simultaneously satisfies the following (A), (B), and (C). (A) By a laser Raman spectroscopic analysis with a wavelength of 532 nm, a standard deviation δ(R) of an intensity ratio (R value) of an intensity of a D-band (near 1360 cm−1) to an intensity of a G-band (near 1580 cm−1) measured with a beam diameter of 1 μm at 50 measurement points is from 0.01 to 0.07. (B) A BET specific surface area SBET is from 400 to 1520 m2/g. (C) A nitrogen gas adsorption amount VN:0.4-0.8 during a relative pressure (p/p0) from 0.4 to 0.8 is from 100 to 300 cc(STP)/g. A method of producing such a carbon material for a catalyst carrier is also included.
